Application
In biology, similar to N, N-dimethyl-p-phenylenediamine, it can be used to detect certain oxyreductases.
In photography, it was used in the color development process to process photographic materials with non-diffusing hydrophilic color-forming components. It gives a good yield of the dye, but because of its toxicity, they try to replace it with other color developing substances: CPV-2, CD-2, CD-3, CD-4.
